설치 및 사용
사전 준비
KRX Open API에서 회원가입 후 API 인증키를 발급받으세요.
Claude Desktop
claude_desktop_config.json에 추가:
{
"mcpServers": {
"openkrx": {
"command": "uvx",
"args": ["openkrx-mcp"],
"env": {
"KRX_API_KEY": "<YOUR_API_KEY>"
}
}
}
}
Claude Code
claude mcp add openkrx -e KRX_API_KEY=<YOUR_API_KEY> -- uvx openkrx-mcp
직접 실행
# stdio (로컬)
KRX_API_KEY=<YOUR_API_KEY> uvx openkrx-mcp
# streamable-http (원격, 세션 없는 stateless 모드)
KRX_API_KEY=<YOUR_API_KEY> MCP_TRANSPORT=streamable-http PORT=8000 uvx openkrx-mcp
Docker
docker build --platform linux/amd64 -t openkrx-mcp .
docker run -e KRX_API_KEY=<YOUR_API_KEY> -p 8000:8000 openkrx-mcp
컨테이너는 기본적으로 MCP_TRANSPORT=streamable-http로 기동되며, http://localhost:8000/mcp 엔드포인트로 JSON-RPC 요청을 보내면 됩니다(세션 없는 stateless 모드 — 매 요청이 독립적으로 처리되며 Mcp-Session-Id 헤더가 필요 없습니다).
curl -X POST http://localhost:8000/mcp \
-H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
참고
- 데이터는 2010년 이후 일별 데이터이며, 매일 오전 8시(KST)에 갱신됩니다.
- 날짜 파라미터(
basDd)는YYYYMMDD형식입니다. - API 호출 한도: 10,000건
mcpSDK는>=1.9.0,<2.0.0으로 버전을 고정하고 있습니다 — 2.0.0부터mcp.server.fastmcp모듈 구조가 크게 바뀌어 상한 없이 설치하면 빌드가 깨지니 주의하세요.
